1.2 Aplication
Used actuators allow 3-point controlling or controlling by signal 0(4)-20mA or 0-10V. They can be equipped with the signalization of end positions and transmitter of position.
The valves can be actuated with electric actuators. Producers of actuators are for example ZPA Pečky, Regada Prešov, Auma, Schiebel, Flowserve.
Valves are delivered with weld ends or flanges .Control valves RV 70x have the packing set of “LIVE LOADING” type.
Control valves RV 701 are one-seated valves designed to create a lot of combinations of controlling appliances. Valve is pressure balanced, with multi-step throttling system, designed to be cavitation and noise free. Control valves RV 702 with extended outlet have multi-step throttling system (with orifice plate) designed to eliminate high differential pressures. Valve has pressure balanced throttling system, which assures low noise, low wearing during big pressure drop operation.

1.6 Multi-step pressure reductionFor valves working with above-critical differential pressure or with pressure drop higher then recommended is useful to use two-step or more-step reduction to lower noise, ensure long service life of valve inner parts and prohibit them from cavitation.
1.5 Operating mediumValves are designed to regulate pressure and flow of liquids (RV 701), steams and gases (RV 702) without mechanical impurities. Sort of common operating medium can be water (RV 701), steam (RV 702) and other medium with no special demand on valve body material. Using for some other medium should by consulted with producer.

1.7 Application of orifice plates (RV 702)In case of above-critical flow, the producer recommends to install one or more orifice plates at the valve outlet to stream-line the process medium flow and to lower the noisiness. The concrete valve execution (No. of orifice plates) is designed according to pressure ratio and it is recommend to consult it with the producer.
2. DIRECTIONS FOR INSTALLATION AND OPERATING OF VALVE 2.1 Preparation before installation The valves are delivered from the company assembled, adjusted and tested. Before valve´s installation into pipeline you must check the data on the name-plate with data mentioned in accompanying documentation. Then check if the valve or the actuator are not damaged and dirty. Pay attention especially to inner spaces and packing surfaces of valve.The chemicals are applied during the manufacturing, to preserve the valves prior the corrosion. The protecting solution “Konkor” (oil base) is used at inner surface. The grease is applied at flange's faces or welding ends.In case, the preserving agent should contaminate the medium, it is necessary to rinse/clean the valve with suitable cleaning agent/solution.The flange's faces and welding ends must be prior the installation always degreased.
2.2 Installation of valve into pipelineThe valve must be installed in such direction, that the arrows on the valve body correspond to the process medium flow. The valves with inlet DN 15 – 150 can be installed in any position, except the position with actuator under the valve.For valves with inlet DN 200 - 250, the only possible position is with stem in vertical position and actuator on the top. Protection of actuator against the radiant heat can be necessary in case of high temperature application. As a basic provision can be made pipeline insulation, actuator turning aside from vertical position, etc.. When the valve is installed into pipeline and actuator is turned aside from vertical position then it is necessary to ensure suitable supporting of actuator.For proper function of control valve, below-mentioned instructions must be obeyed:- no excessive forces can be transfered from pipeline to valve.- the pipeline must be cleaned from dirt before valve installation. - the valve can not be installed just behind the bend. Pipeline should be straight min. 6x DN in front of the valve. For 702 RV, the length of straight outlet section shall be 20 times the outlet DN, but in all cases a minimum of 4m.- the inlet valve DN 150 until 250 must be adapted to the space above the valve, so that it was possible to use the lifting device.- it is recommended to keep clean space around the valve for easy manipulation and service.- installation itself must be done precisely.

2.2.1Actuator´s connection to electric networkThese works can be done only by the experienced workers. It is necessary to keep all safety rules. It is also necessary to follow instructions for installation, operating and service of electric actuator published by producer. Transmitter of position and signalization switches are placed under the cover of actuator, in the case they are as part of the delivery.In regard of the valve being delivered assembled together with its actuator from the company, basic adjusting and setting of actuator is carried out. The valve is adjusted in closed position by torque switch (so that the valve will be really tight closed) meanwhile the switching off the actuator is adjusted in open position by limit switch. In case the actuator is dismantled from the valve body for any reason such as the valve installation into pipeline etc., it is necessary to check the setting again after the assembly possibly to carry out the complete setting of actuator again. Producer does not take over the guarantee if the damage was caused by improper setting or adjusting of the actuator. In case of need, it is possible to ask for such service from service organization of the producer.The length of the cables to actuator should be selected so that the actuator could be disassembled from the valve without any need for the cables unplugging from the actuator’s terminal board.WARNING: It's necessary to observe the mechanical stroke indicator placed at actuator's joke or directly at the electromotor, if the valve is operated (opened or closed) by hand wheel. The extra care must be taken near to OPEN and CLOSE position. Neither position nor torque switches are in function in such case and there is a danger of valve or actuator serious damage. It's strongly prohibited to use any mechanical tools (force boosters) for hand wheel operation. 2.2.2 Pneumatic actuator connectionThese work may by carried out by trained personnel only. It is necessary to follow instructions for installation, operation and maintenance of pneumatic actuators issued by the producer of the actuator. Connection of pneumatic actuator to air supply is done by plastic, copper or stainless-steel tubes, recommended dimension is 8x1 mm. The 12x1 mm tubes are recommended for the actuators with membrane
2area larger than 600 cm or in case the length of air pipeline is more than 10m.Before valve commissioning, the data, given in the actuator and positioner ID plate (especially air supply maximum pressure), should be checked/compared with given specification. If the pressure of air supply is higher, the pressure reduction valve must be used.As the valve is supplied with actuator as a complet, the basic setting is also carried out. In case the actuator was removed from the valve, it is necessary to check this setting or set the actuator once again. The producer does not take over the damage caused by wrong setting of the actutor. In case of need, the assistance of our subsidiary LDM Service can be required.In case of pressure air regulator (air supply to pneumatic actuator) fixed directly on the valve/actuator yoke, the regulator must be placed in vertical position (draincock/draincup down), see picture. If the valve mounting position is known during the valve-actuator assembly, the right position is set on the production line/during final test.
2.2.3 Checking after installationPiping system should be pressured after valve installation and then checked if there is no leak. Check the packing set tightness as well. Then check the proper function of actuator by doing a few strokes.Maximum allowed pressure for LDM „live Loading“ packing is 25 MPa. In case, the test pressure is higher, the test packing must be used.
2.2.4 Cleaning of pipeline
In case, the pipeline is cleaned by flushing, blowing out after valve installation, the following provisions must
be done: - the inner/control parts must be removed (plug, stem, seat cage)
- the hole for stem in valve cover must be blinded
Valve disassembly and also the back assembly of parts including the actuator assembly and setting must be
done by authorized organization (LDM Servis s.r.o.). If not, the warranty is no more valid.

PM - 077/20/04/GB_RV 70x 10/13
2.3 Operating and ServiceThe valves are equipped with graphite packing rings. The packing set is loaded with system of disc springs "LIVE LOADING". During the operation, it is necessary to maintain the gap between the flange and packing bushing in the range 0,5 - 1,5mm (pic. No.1). From the factory, the value of 0,5 mm is set. The tightening is carried out by four nuts M12. The producer recommends to check this value more often (about twice a month) after starting new packing set. Later, once a half of year is enough.The stem must not be lubricated operation.
2.3.1 Exchange of packing setIf there is a need to exchange the packing because of worse tightness, it’s recommended to ask LDM service company for technical instructions for dismantling and assembly of the "LIVE LOADING" packing or to ask them for a exchange of it.
2.3.2 Electric actuatorsElectric actuators have to be operated according to instructions given in „Actuator manual”. In case of malfunction of actuator, see the instructions or ask for professional repair man.
2.3.3 Warming-through and putting fittings out of operationWarming-through fittings:Fittings have to be filled and warmed-through by regulating the steam supply and drainage so that the trend of the temperature increase is observed, i.e. so that the increase in the temperature of fittings does not exceed the given temperature jump per minute (see the table). After the required temperature is reached, the operation of the steam piping is regulated depending on the need of the given appliance.
If the required temperature of the fitting needs to be reached faster, it is necessary to secure permanent warming-through, e.g. by means of a by-pass.
Putting fittings out of operation:If possible, the decline of the temperature of alloy steel fittings that are cooling down is to be as slow as the temperature increase in warming-through. If a faster temperature decline is detected, the decline has to be slowed down until the temperature drops to 300 °C; then the piping is let cool down without any intervention. The cooling rate does not have to be monitored in fittings made of carbon steels.
2.3.4 Thermal and acoustic insulationThe type and dimensions of the insulation are as stated in the design. Only the insulation above the cover of the fitting has to have its height adjusted to provide a free access for monitoring the compression of the packing or for tightening (see point 2.3, pic. 1).
2.4 Elimination of defects and malfunctionsIf a defect is detected on the valve (leakage, leakage of packing or bonnet sealing, etc.), it is necessary to ensure its repair immediately otherwise a permanent damage may occur to sealing surfaces and other parts exposed to effects of leaking medium. Prior to any repair work on the valve, make sure that piping system is free of pressure!
